BERTHA sJsTni/r, orh Los ANGELES, CALIFORNIA MANUALLY-OPERATED IRRIGATOR Application filed July 20,

My invention is a manually operated irrif gator adapted for attachment to a hose or the like, and is adapted to give a wide anda narrow water spray. A

An object of my invention is a water irrigator having a casing adapted for connection to a pipe to which a hose may be attached.` The casing has a rowof perforations in alignment for discliargingwater,and the` supporting metal-at these perforations forming the nozzle jets is given a bend, positioning the nozzle jets at an angle to thev plane of the end of the casing. The back .of the lcasing from the forward end, through which the jets extend, is tapered rearwardly and inwardly.' The top and bottom sides diverge slightly -i'rom the face having the nozzle or jet openin Y gA turtherobj ect of my invention is the construction of a Water irrigator in which certain of the perforations at each side of the center perforation are vinclined inwardly towards the center to such an extent that the streams of water diverging in the irrigator from the attachment to the handle are diverted to form parallel jets ot Water in alignment with the center stream from'the center jet.

My invention is illustrated in the accompanyi-ng drawings, in which: Figure 1 is a' perspective view of my irrigator showing the manner of'use Figure 2 is a face elevation taken in the direction of the arrow 2 of Fig. 1.

. Figure 3 is a horizontalsection on the line 3 3 of Fig. 2 in the direction of the arrows. Figure 4 is a side elevation taken in the direction of the arrow 4 of Fig. 3.

The'irrigator comprises'a casing 11 which has upper and lower walls 12, a front face 13, two end walls -14 and rearwardly and `inwardlyconverging rear walls 15. Viewed from the face in a horizontal View, as shown in Fig. 2,v it willibenoted that the ends 16 have the ytop and bottom walls substantially parallel and at the center 17 there is a swelling or spreading apart of the top and bottom walls. In other words, these walls diverge from the face 13, and these top and bottom walls and the rear walls 15 are at- 1927. serial no. 207,076.

tached to the coupling 18 which has a screw- Y threaded socket 19. A handle pipe 20 may be secured in this socket and a hose 21 secured to the handle. The tace of the casing has a series of perforations 22 adjacent the yend which are punched or cut through a portion 23 of the front wall which is flat. Thenext series of nozzle jet perforations 24 have the wall kinked or bent as indicated at 25, so that the center linev of these nozzles is inclined inwardly, as indicated by the line 26 5 whereas the axial center of the `nozzle jets22 is. at right anglesto the tace 13, as indicated by the center line 27. The center perforation 28 is in a iiat section 290i the front yface and its axial line 30 is at right angles to the front face 13. I t

' In constructing the casing in forming the irrigator it is not necessary that the front tace have right angular corners joining the top and bottom walls 12, as these may be mergedjwith a round curve. I lind a convenient way to manufacture the irrigator with the nozzle jets inclined at an angle is to have these :aperturesperforated lwith their axial lines at right angles to the front face 13 and then witha round implement inserted through the nozzle, to bend the adjacent metal, inclining the axisot each nozzle inwardly on opposite sides of the center.

The manner of operation and functioning of my irrigator as thus constructed is substantially as follows:

On account of the water having a freer flow directly from the pipe 20 at the center of the casing in the ordinary construction with the jet nozzles all at right angles to the front face, a Vgreater lowof water would pass through the center than at the sides, and thus the spray would not be even. However, with my construction, the water jets are even from one end lto the other of the front face andthusgivewan even spread of thel water, with substantially as much water flowing through the nozzle jets 22 adjacent the opposite ends of the casing as through the center nozzle jet 30, or the inclined jets 24. Therefore, in watering plants, or irrigating, when the irrigatorjcasing is moved 100 I handle. The jet openings lat'each side of ythe center have their axes pointing towards the axis of this center jet so that as the waterV in the casing 11 having a direction of flow towards the ends 14; is diverted to such an extent that the jet of water from each of the inclined orifices is parallel to the center stream 30. The water that passes out of the jet orifices adjacent the ends 14 has been given aslight turn in direction by the inclinedback 15 so that these jet orifices may have'their axes parallel tothe center jet and give a series ofparallel streamsof water. The inclination ofthe axes of the openings is to Ydeflect water which flows in a forward and an outward direction-to a direction which is parallel to the axis of the center jet 30.

Various changes may be made in the principles of my invention without departing. from the spirit thereof, as set forth in theV description, drawings and claims.
